merge threads

I've searched this topic and cant seem to find an answer. I want to merge a thread. I am the admin so I click on merge thread link at left of message. This takes me to a widow that says:

"Merge Thread with:

Now go to the thread which should be merged with the selected thread and select 'Merge Thread' again."

So how do I get back to the thread I want to merge with, without hitting the back button on my browser? when I do I lose the window and the option to merge a thread. Do I open a separate window? Very frustrating and not intuitive I must say.
